The chemical compound "6-<4-(2,3,4,6-Tetra-O-acetyl-β-D-glucopyranosyloxy)phenyl>-5,6-dihydro-2H-pyran-2-on" is a complex organic molecule with a unique structure. It features a pyran-2-on core, which is a type of heterocyclic compound with a six-membered ring containing one oxygen atom. The molecule is further characterized by a phenyl group attached to the pyran ring, which itself is substituted with a tetra-O-acetyl-β-D-glucopyranosyloxy group. This group consists of a β-D-glucopyranosyl moiety, a type of sugar derivative, with four acetyl groups (-COCH3) attached to the hydroxyl groups, indicating a high degree of esterification. The compound's complexity arises from the combination of these functional groups, which may have implications in various chemical and biological contexts, such as in the synthesis of pharmaceuticals or the study of complex carbohydrates.
The CAS Registry Mumber 4583-57-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,8 and 3 respectively; the second part has 2 digits, 5 and 7 respectively. Calculate Digit Verification of CAS Registry Number 4583-57: (6*4)+(5*5)+(4*8)+(3*3)+(2*5)+(1*7)=107 107 % 10 = 7 So 4583-57-7 is a valid CAS Registry Number.
